And so the iOS-ification of Mac OS X continues. Apple has just announced that all applications submitted to the Mac App Store have to use sandboxing by March 2012. While this has obvious security advantages, the concerns are numerous - especially since Apple's current sandboxing implementation and associated rules makes a whole lot of applications impossible.

No I didn't read the entire article; it's a big rant with a small amount of useful content. The title and introduction are still misleading; it should be clear in one of these instances that this is not an introduction of the sandboxing requirement. This has been set in motion for a few months now and it's just getting an extension. You mention it a good 7 paragraphs into the article. Most people will probably skip it, it's just bad journalism.
